This methodological research is aimed to examine the effectiveness of the methods used to estimate the internal length of the nasogastric tube and to determine the most reliable method for correct placement of the nasogastric tube in adults. The study will be carried out between 01 September 2022 and 01 September 2023 with 155 patients who hospitalized in the anesthesia and reamination intensive care and general intensive care units of Aydın Adnan Menderes University Application and Research Hospital. The internal tube length measurement methodologies will utilized to confirm proper NGT placement. A total of 5 groups will be included in the study, including 1 control (NEX measurement method) and 4 experimental groups, (Experiment 1: CoNEX measurement method, Experiment 2: XEN+10 cm measurement method, Experiment 3: GWNUF measurement method, Experiment 4: EXU-NE Method measurement method).The "gold standard" reference method will used for comparison was radiography. Research data will be analyzed in SPSS (Statistical Package for Social Sciences) for Windows 25.0 statistical package program. Descriptive statistical methods (number, percentage, mean, standard deviation) will be used in the evaluation of the data. The comparison between the methods used in the measurement of the nasogastric tube (NEX, CoNEX, XEN+10 cm, GWNUF, EXU-NE) and the results of the radiological evaluation (reference method) will be made with Chi-square analysis. Statistical significance will be accepted as p\<0.05.

The CoNEX method is an effective measurement method to accurately determine the internal length of the nasogastric tube.
By creating a straight line with a tape measure, first the distance between the patient's nose tip and the earlobe and then the distance between the earlobe and the xiphoid will be measured, then the nasogastric tube length to be applied to the patient will be determined according to the (NEX x 0.38696) + 36.37 cm formula. The length determined according to the result will be marked on the nasogastric tube, and the nasogastric tube will be advanced by the researcher from the patient's nose to the marked place.Immediately after the completion of the insertion process, an abdominal X-ray will be taken and the tube location will be confirmed.

The XEN+10 cm method is an effective measurement method to accurately determine the internal length of the nasogastric tube.
By creating a straight line with a tape measure, the distance between the patient's xiphoid and earlobe, then the distance between the earlobe and the tip of the nose will be measured and 10 cm will be added to the measurement obtained. The location of the tube will be confirmed by taking an abdominal x-ray immediately after the placement process is completed, the position of the distal end of the tube relative to the gastro-esophageal junction will be measured and recorded.

Corrected nose-earlobe-xiphoid measurement method (CoNEX), (n=31) The distance between the patient's nose tip and earlobe will be measured first, and then the distance between the earlobe and the xiphoid, The nasogastric tube length to be applied to the patient will be determined according to the formula (NEX x 0.38696) + 36.37 cm, The length determined according to the result obtained will be marked on the nasogastric tube, The nasogastric tube will be advanced by the researcher from the patient's nose to the point where the marking is made, Immediately after the completion of the nasogastric tube placement procedure, an abdominal X-ray will be taken to confirm the tube location, the position of the distal end of the tube relative to the gastro-esophageal junction will be measured and recorded.
Different Internal Tube Length Measurement Procedures will used for the correct placement of nasogastric tube.
